The detection and forecast for geological structure ahead of the tunnel and laneway is a very difficult problem in the world. Many applied researches based on the method of the seismic reflection wave have been done in our country from 1990, and many successful practical examples are obtained. At the same time, the detecting methods also have different problems. The main methods using reflection wave principle for forward prediction in the word include different forms, such as TSP, negative watching velocity, HSP, TRT, ISIS, and landsonar method, and so on. This article illustrates briefly the principle of different methods, and analyzes the status-quo of application and research of the forward prediction technology in China. The existing shortage in data collecting and processing of forward prediction ahead of tunnel and laneway is pointed out. The authors believe that the researches of the forward model and inversion theory, data collecting system in 3D complex space, migration imaging technology, etc, should be concerned in forward prediction and forecast. The aim of forward prediction is to establish and consummate the dynamic system of real time watching and forecasting for geological structures ahead of tunnel and laneway.
